T o all whom it may 'concern Be it known that we, ANDREW C. KLEIN and STEPHEN L. KiiEIN, citizens of the United States, residing at Reading,` in the county of Berks and State of Pennsylvania, have invented Certain new and useful Im` provements in Gasolene-Engines, of `which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to explosive engines7 and has particularly Afor its objectthe production ot an engine without crank case compression Vor extra cylinder -to compress the charge before entering the combustion cylinder, and an eiicient exhaust mechanism therefor, whereby an eiiicient means has been produced for removing the burned gases from the cylinder.

Another object of this invention is vthe production of an efficient means carried by the outer end of the exhaust discharge whereby the'suction of passing air will cause an efiiclent means for drawing the burned 'gases from the cylinder of thevengine.

The-present device is especially adapted for use upon moving vehicles since unless the vehicle is in motion, the suction means carried by the outer end of the exhaust pipe will not operate.

In the drawings: Figure 1 is a side elevation. Fig. 2 is a vertical section through the of the spark plugs, Fig. 3 is a transverse sectional view through the explosive cylin- Fig. i is a plan view of one end of the exhaust pipe showing the arrangement of the ports. Fig. 5 is an Fig. 6 is a detail vperspective View of the lower end of the supporting standard for the valve triger. g Referring to the drawings by numerals it will be seen that l'designates the explosive cylinder and forfthe purpose of insuring an eiiicient explosion 'two spark plugs 2 are employed, said plugs being fitted in thc upwardly extending sleeve portions 3' formed upon the upper end of the engine. The explosive cylinder is provided with the usual radiating rings 4:. An auxiliary casing 5 is carried by the upper end of the cylinder 1, and to this casing is connected the fuel supply inlets 6, said supply inlet communicating Specification of Letters Patent.

Serialito.6943088; l, I- i' i 'l with the compartment formed thev caslstem passes throughI a boxing 10. Tlie sleeve I 9 carries a collar 11, and between' this collar 11, and the upper end of tho casing: jis

interposed a tension coil spring l2. `A Vhead 13 is formed upon the upper endet the stein 9, and upon this headl rests the outer' end@y of.l

the triggcr'lt. The rear end of thetrigger 14 'is connected to a 'rod 15 which may ,befopcrated .by any suitable means 'forcausing the.

end to depress the plunger 9, and cause the valve 8 to open for relieving compression whereby the 'engine maybeeasily started,

A trigger14 is. supportedby means of la standard 16, said standard 16 havirngade-- pending threaded portion 17 which threaded portion fits in the upper end of the cas`l ing This'tri'gger 14 is supported`v by means of a yoke portion 18 carried by the upper end of the standard 1G. The standard 1G is provided with a broad flat base 19 which forms an efficient support for the standard and braces the same against. lateral swing upon the casing 5. u

It will be seen that the overhanging flange 2O of the boxing l() will prevent the aecidental removal of the lower end of the coil spring 12 from its scat.

The exhaust ports of the cylinder are formed at the cxtreme lower end of the stro-ke of the piston 21 upon each side as indicated at 22. These exhaust ports communicate with the ends 23"of the exhaust pipes 24 which ends 23 are provided with apertures 25 for communicating with the apertures 22. The pipes 24 terminate in a common exhaust discharge pipe 2G, which pipe carries at its outer end a funnel shaped hood 27. This hood is supported upon the outer end of the pipe 26 by means of brackets 29. The hood 27 is so placed upon the exhaust pipe 26 as to have the wide cud near the front and tapered toward the open end of the pipe 2G. It should, of course be understood that this pipe 26 may be so formed as to have the funnel shaped hood 27 carried in the most convenient place upon the vehicle so that the same will be freely engaged bythe passing air.v

From the foregoing description.. it will be y scribed, as soon as the piston 21 reaches its lower extreme stroke, the exhaust gases will rush out throughA the apertures 22, out through the ipe 26, and be discharged from the outer en 28. When the vehicle 1s traveling,

caused by the vexhaust from the exhaust pipe 26. It should, however, be understood that1 the discharge apertures formed in the cylinder are of sufiicient size and number to allow a great quantity of the exhaust gases to pass therethrough thereby eliminating the necessity of applying any additional suction means, such as a pump or the like. Of course, as s oon as the exhaust is drawn from the cylinder after the explosion, the new gases will be admitted into the explosive cylinder by reason of the fact that the valve will yield and cause the fresh gases to pass into the eX- plosive cylinder' ready for the new explosion. The spring l2 is of the 'conical spiral type as illustrated for causing the same to be very sensitive thereby insuring rapid operation ot the valve.

The rocker arm 14; and valve mechanism described are adapted to relieve compression to make the starting of the engine easy. As stated above this rocker arm' may be opera suction through the pipe 28 will be', the rush of the air through the*- iunnel hood 27 thereby efficiently drawing" ated ,through a push rod of the ordinary type which maybe operated from the handle of the motorcycle, upon an automobile as to be convenient when cranking the machine. y f What is claimed isz- A11 engine of. the class described comprising la ,cylinder provided with .sets of open- `ings'in'the side walls thereof, a pipe prolvided. with branches communicating with openiii s in said cylinder upon opposite sides thereo said b'ianche's of said pipes extending beyond` the sides of said cylinder to facilitate the cooling of the exhaust as they saine-passes from said cylinder, a tapering hood, brackets secured to the outer end of said pipe and engaging the inner face of or may be so placed said hood for holding the same in spaced relation relative to said pipe, and said hood projecting beyond the outer end of said pipe to facilitate the passage of air through said hood and pipe as the exhaust is discharged from said pipe.
